Lapho kukhiqizwa ama-Precision Bearings, kungani umshini wokucija udingeka, iyini imisebenzi yawo, futhi inqubo yokucija yenziwa kanjani ngokuqondile?

1. Kungani Umshini Wokujuba Udingeka Ekukhiqizeni I-Precision Bearing Manufacturing

Ukuhlonishwa kuyadingeka ngobaama-bearings adinga ukunemba okuphezulu kakhulu kwe-dimensional, ukujikeleza, isilinda, nokuqedwa kwendawoezingxenyeni ezifanaizindandatho zangaphakathi, izindandatho zangaphandle, nemikhono yokuthwala. Ukugaya kukodwa akukwazi ukuhlangabezana ngokugcwele nalezi zidingo ezinembayo ngenxa yokucindezelwa kwendawo eyinsalela,{1}}ubunzima obuncane, nokuhlanekezeka komumo.

Izizathu Eziyinhloko:

Ukuthola Ukunemba Okuphezulu-Okuphezulu Kobukhulu

Ama-Bearings ngokuvamile adinga ukubekezelelana ku-micron noma sub{0}}ibanga le-micron ( Ngaphansi noma kulingana no-1–2 μm).

I-Honing isusa ama-micrometer ambalwa wokugcina wezinto ezibonakalayo ukuze kuzuzwe lokhu kubekezelela ngemva kokugaya noma ukwelashwa kokushisa.

Ukuthuthukisa I-Surface Finish

Ukuzalanisa ama-raceways nama-bores kudinga ukuqeda ebangeni leI-Ra 0.02–0.2 μm.

Ukujula kuqeda izimpawu zokugaya futhi kudala ithafa-elifana nendawo ukuze kugcotshwe kangcono futhi kuncishiswe ukungqubuzana.

Ukulungisa Amaphutha Ejiyomethri

Ilungisa amaphutha emimo emincane njengengaphandle-kokuzungeza, ukucisha, kanye nokuphaphazelaokubangelwa izinqubo zangaphambilini.

Iqinisekisa ukuthi imigwaqo yomjaho kanye ne-bores i-cylindrical ngokuphelele futhi i-coaxial.

Ukuthuthukisa I-Wear Resistance kanye Nempilo Yokuthwala

Indawo ephucuziwe igcina amafilimu e-lubricant ngempumelelo kakhudlwana, yehlisa insimbi-kuya{1}}kukuxhumana kwensimbi.

Yehlisa ukushisa okungqubuzanayo futhi ithuthukise impilo yokusebenza.

2. Imisebenzi yomshini wokucija ekukhiqizeni i-Bearing Manufacturing

3. Indlela Inqubo Yokujuba Yenziwa Ngayo Ngokuqondile

Ukusebenza kokucija ama-bearings kuncike engxenyeni (ring yangaphakathi, iringi yangaphandle, noma umkhono), kodwa ngokuvamile kulandela lezi zigaba:

Isinyathelo 1: Ukulungiselela

Isiqeshana sokusebenza (isb., ukuthwala iringi yangaphakathi) siyaqina futhi sigaywe kuqala.

Indawo ephucuziwe (imvamisa ibhore noma umgwaqo womjaho) iqondaniswe ku-aovundlile noma mpo umshini honing.

Isinyathelo sesi-2: Ukukhweza Ithuluzi Le-Honing

A honing mandrel noma umhlangano itsheifakwa ebhoreni.

Ithuluzi hasamatshe abrasive(idayimane, i-CBN, noma i-aluminium oxide) enwebeka ukuze ixhumane phezulu.

Isinyathelo sesi-3: Ukucija Isenzo

I-mandreliyazungeza futhi iyabuyiselakanyekanye.

Okuhlanganisiwei-rotary + ephindaphindayoukunyakaza kudala okulawulwayoiphethini ye-crosshatch.

Ukucindezela kokuphakelayo kusetshenziselwa ukwandisa amatshe kancane kancane njengoba kukhishwa impahla.

Amapharamitha ajwayelekile:

Isivinini: 100–600 rpm (i-rotary)

I-Stroke: 10–50 mm/s (ukuphindaphinda)

Ukususwa kwesitoko: 2–20 µm

Isinyathelo sesi-4: Ukulinganisa kanye Nempendulo

Emigqeni enembayo enembayo,{0}}enqubweni yokukala kuvame ukuhlanganiswa.

Usayizi we-Bore kanye ne-geometry kugadwa-ngesikhathi sangempela, kulungiswa ngokuzenzakalelayo okuphakelayo ukuze kugcinwe ukubekezelelana.

Isinyathelo sesi-5: Ukuhlanza nokuhlola

Ngemva kokucija, i-workpiece iyahlanzwa ukuze kukhishwe ama-abrasives nezinsalela zamafutha.

Ukuhlolwa kobukhulu kuqinisekisa:

Ububanzi bebhore ngaphakathi ±1 μm

Ukujikeleza Ngaphansi noma kulingana no-0.5 μm

Indawo eqeda u-Ra Ngaphansi noma ilingana no-0.1 μm

5. Isifingqo: Kungani Ukucija Kubalulekile
